Hello, Is there any way to organize logbooks in some kind of tree with sublogbooks or just have a subdirectories in a logbook directory on the filesystem (treat it as a sublogbook if its name is different from 4 digits of year and pin above all the entries in a list) to structure entires a bit?

Attached the shell scripts using awk and sed how I have migrated two separated logbooks into one single and how I re-adjusted certain attributes.

Dear all,

 

I had some difficulty to upload large files (>20MB) with SSL connection. I think it is also related to https://elog.psi.ch/elogs/Forum/68636

During debuging, I found that, when uploading large files, ssl connection is dropped since 'SSL_read' function returns -1.

But it doesn't alway mean broken connection. It may be "SSL_ERROR_WANT_READ".

I changed the "server_loop" function in the source code to "continue" when it is SSL_ERROR_WANT_READ. And it fixed the problem.

Here is my code.


## elogd.c "server_loop" function L30031

                        if (FD_ISSET(_sock, &readfds)) {
#ifdef HAVE_SSL
                          if (_ssl_flag){
                            i = SSL_read(_ssl_con, net_buffer + len, net_buffer_size - len);
                            if(i<=0){
                              int ssl_error=SSL_get_error(_ssl_con,i);    ## check ssl error code
                              if(ssl_error==SSL_ERROR_WANT_READ||ssl_error==SSL_ERROR_WANT_WRITE) continue;    ## if ssl wants more, continue
                            }
                          }
                          else
#endif
                            i = recv(_sock, net_buffer + len, net_buffer_size - len, 0);
 


 

I am ignorant about networking. Some experts on ssl connection would know a better way to deal with this problem.

 

Best,

HyonSan Seo

That would be a nice feature...

If you are good in parsing HTML you can achieve this feature: when you create a new entry "<elog-URL>?cmd=new", you'll get HTML source code that provides you with all possible attribute choices.

Disclaimer: this only works if you don't use Conditional attributes.

Hey,

I'm trying to integrate the Elog into our SlowControl System (Phoebus/EPICS). As a first step I translated the python library to Java. So writing new Entries and viewing them works.
But for Phoebus, you need a list of the possible values for the attributes. Currently this is done via the config file from Phoebus.

Is there a way to get the values also via a query directly from the Elog?

Cheers,
Florian

 

  69235   Tue Oct 20 02:34:46 2020 Idea Anthony Krishockajkrishock@verizon.netQuestionWindowslatestField values dependent on other selections

All,

I would like to know if there is a way in elog to populate a field based on the value of another field. What I want to do is have a field with a few selections (a menu) and another text field that populates based on what I select from the menu.

 

Is this possible?

Hi Stefan,
no problem: if I just strip all newlines from the $text field (in HTML you use <br> anyway, the newline has no function apart from whitespace), and my multiline attribute is fine to go.
I do not intend to make the attribute editable: it is just used for display. Because that allows me to create the attribute either from free text or from combining other fields - depending on conditional attributes.

As a special feature you could strip all newlines beforehand, when providing the $text for subst statements.

Cheers, Andreas

Sure, attributes can be shown multi-line, but they cannot be stored in the elog internal database. The database is a very old design and only allows for single line attributes. Just look at a YYMMDDa.log file and you will see that. I would have to change the database format to somethign more advanced like XML, but that would take me a couple of weeks or months.

Soooorrryy! ;-)

Andreas Luedeke wrote:

While the input widget of text attributes is a single line, they can easily be multi-line in the display - when you use HTML at least.
And of course the user can parse the text field and generate a single line, if he wants to.
If you leave it to me, I'll create wonderful applications to that feature :-)

Please? ;-)

Stefan Ritt wrote:

$text is the full body text and can go over many lines. Since attributes are restricted to single lines, it's not possible to substitute them with the body text.

Hi Stefan,

I've just tried to read the $text with subst into another field and failed.
It looks like $text is only available for the execution of shell scripts in the "execute new|edit|delete = <script>" command.

Could that be added? I can think of a multitude of applications:

  • In my case I want to fill an attribute X either with free text or generated from other fields. The list view will show just X and not how it was generated.
  • I could fill an attribute automatically with the character length of the text.
  • I could parse the text in a shell script and set other attributes according to the content.

Thank you for considering it.

Cheers, Andreas
